groupNcolor: Assign Group Membership and Colors for a Spectra Object

Description

A utility function which looks for gr.crit in the file names of .csv files and assigns group membership. Also assigns a color, a symbol and an alternate symbol to each group. Warnings are given if there are file names that don't match entries in gr.crit or there are entries in gr.crit that don't match any file names. Not intended for users.

Usage

groupNcolor(spectra, gr.crit = NULL, gr.cols = c("auto"))

Arguments

spectra
An object of S3 class "Spectra". Until this function acts on spectra it is not quite complete.
gr.crit
gr.cols

Value

  • A complete object of S3 class "Spectra". Until this function has done its job, an object of class "Spectra" will not pass checks as the assembly is not complete (see chkSpectra).)
